A new signaling scheme for one-shot near-far resistant detection in DS/CDMA
Fu‐Chun Zheng, Stephen K. Barton · 2002
This paper proposes a new signaling scheme: orthogonal on-off BPSK (O/sup 3/BPSK), for near-far resistant detection in the asynchronous DS/CDMA systems (up-link). The temporally adjacent bits from different users in the received signals are decoupled by using the on-off signaling, and the original data rate is maintained with no increase in transmission rate by adopting an orthogonal structure. The detector at the receiver is a one-shot linear decorrelating detector, which depends upon neither hard-decision nor specific channel coding. Some computer simulations are shown to confirm the theoretical analysis.
